Apache Tomcat on Ubuntu 26.04

Apache Tomcat is an open-source Java-based web server and servlet container developed by the Apache Software Foundation. It is used to run Java web applications by implementing core Jakarta EE specifications such as Servlets, JSP (Java Server Pages), and WebSocket support. Tomcat is lightweight, fast, and widely used for deploying and managing Java-based web applications in development and production environments.

• High-performance HTTP server for handling web requests.
• Easy deployment of WAR (Web Application Archive) files.
• Simple configuration using XML-based setup files.
• Cross-platform support (Linux, Windows, macOS).
• Integration with databases and external application services.
